Newbie: Recursive deletion of files and dir

ruby-talk
1

Hi!
I'm designing (newbie level) a script to clean up empty directories and
old files recursivly. Something is wrong..works fine when not actually
deleting anything, but when I start removing files and directories it
ends prematurly.. any heklp available..?

def thisDir(dirname,f)
  Dir.chdir(dirname)
  currDir=Dir.getwd
  nf=0
  nd=0
  fs=0.0

  if Dir.entries(currDir).size>2 then
    Dir.foreach(currDir) {|x|
    if FileTest.file?(x) && (Time.now-File.mtime(x))/(60*60*24)>15 then
      f.puts("deleting file"+x)
      nf=nf+1
      fs=fs+File.stat(x).size
    end
    if FileTest.directory?(x) && x!="." && x!=".." then
      lV=thisDir(x,f)
      nf=nf+lV[0]
      nd=nd+lV[1]
      fs=fs+lV[2]
    end
    }
  Dir.chdir("..")
  end
  if Dir.entries(currDir).size<=2 then
    Dir.chdir("..")
    f.puts("deleteting this directory:"+currDir)
    nd=nd+1
    #Dir.delete(currDir)
  end

  #Dir.chdir("..")
return [nf,nd,fs]
end
outFileName="cleaned-"+Date.today.to_s+".log"
f=File.new(outFileName,"w")
values=thisDir("./",f)
puts "Deleted "+values[0].to_s+" files"
puts "Deleted "+values[1].to_s+" directories"
puts "Total size deleted:"+(values[2]/(1024)).to_s+" kB"

Any advice is appriciated

I did not read this code yet but take a look at ri FileUtils,
it has useful methods including two that might be handy here:

  FileUtils.rm_rf
  FileUtils.mkdir_p
